This document discusses how cities are hubs of mobility and circulation at various scales, from individual to global. It argues that modern planning envisioned mobility and transport improving urban life, but the reality is more complex. While elites benefit from new hypermobile lifestyles, the majority have less control over their mobility and may face barriers. Cities are central nodes in global networks of finance, trade, migration and communication, but this unevenly impacts populations. Mobility is now commodified and some groups are forcibly immobilized as a form of social control. Overall mobility patterns reinforce uneven development within the unequal geographies of global capitalism.
